Making Rules for Global Finance: Transatlantic Regulatory Cooperation at the Turn of the Millennium

This article explains a shift in the way transatlantic authorities managed conflicts over the cross-border regulation of securities markets: from cooperation skewed heavily toward the preferences of U.S. officials and accepted grudgingly by European counterparts; to a Euro-American regulatory condominium characterized by close interactions among decision makers and mutual accommodation. In the final decades of the twentieth century, the asymmetric influence wielded by U.S. securities market authorities had few parallels in other regulatory areas. Why, then, did U.S. officials become more accommodating and European authorities more influential, and why did the turning point occur in 2002 and 2003, an unlikely moment for intensified transatlantic sovereignty sharing? My study shows that institutional change inside the EU recast the North Atlantic balance of regulatory leverage and thereby was the primary factor behind the reshaping of transatlantic cooperation. Internal EU regulatory centralization changed the expectations of U.S. and European firms and authorities and generated new incentives in Washington, D.C., for accommodation and closer transatlantic coordination. My explanation differs from models that, accepting U.S. financial pre-eminence as a given, attribute variance in cross-border regulatory cooperation to factors such as incentives derived from the particularities of issue areas or preferences rooted in domestic politics. While resonating with a well-established theme from the realist branch of IPE, my findings have broad theoretical significance, and open new avenues for dialogue between realists and constructivists about the social, political, and institutional foundations of power in global economic affairs. The transatlantic political process set off by financial transformation in Europe reveals contemporary sources of systemic change and raises questions about what the EU's ascendance as a global financial regulator will mean in the aftermath of the late-2000s crisis.
